Air con still smells even after air-con service
Last summer my air con started smelling. Over the winter it went away. It was back again at the start of this summer so got Hitchin Audi to do an air con service (they actually did the desanitising process twice so I know it's been thoroughly cleaned out). But just three weeks later, the smell has come back.
Here are the exact symptoms:
- The smell is there when I first start the car and interior fans begin to blow (whether with air con on or in "econ" mode). After a minute or so the smell usually goes away, though occasionally I will get a slight whiff half way into a journey.
- If I stop the car/fans then restart within an hour or so then there is no smell. It is only noticeable on start up after the car has been resting for at least a couple of hours. It seems like the longer it's been resting, the worse the smell.
- The smell is difficult to describe - nothing like what others have described (e.g. musty, BO, mouldy cheese, cats pee, eggs, etc). The closest I can think of is a pungent pollen smell - as though you're walking through a field of oil seed rape, or flowers which are well past their best and beginning to decay. It's quite unpleasant.
I've had the pollen filter changed so it's not that. Any ideas gratefully received!
